[BUG][1.103]: Serios bug with EnergyNet

Now i try update my addon for IC 1.103 and found very serious bug at EnergyNet in 1.103.
Forge version: 3.4.9.171 and lower.
Energy net not update when we break cables between Storage Container. If we break cable, connection not lost, and energy continuous transmit through air.
Sample:
1. Add 2 MFSU and 1 generator for first MFSU.
2. Connect 2 MFSU through cables. Now energy transmited from first to second MFSU.
3. Break cable and energy continues transmit....
I try it for clear minecraft 1.2.5 + forge and no mods in folder.
I spent a lot of time in search of mistakes in my addon code, but error in EnergyNet at 1.103 version.
In IC 1.97 all works fine.

It is a pity that didn't see this subject earlier, it would keep to me a lot of time for search of mistakes in my addon
